VISE.

Application led March 26, 1926.

My invention relates to vises of the type comprising a base presenting a portion against which the article', as for example a pipe, to be clamped, is seated, a flexible element by which the article is clamped in the vise, and means for tightening the element against the article; myprimary object being to provide a novel, simple, inexpensive, and durable construction of vise of the type referred to and one by which the flexible element may be quickly rendered taut or loose, at will, and which will require the exertion of a relatively slight amount o force only by the operator.

Referring to the accompanying drawings:-

Figure 1 is a plan view of a vise embodyino` my invention, the handle portion. the flexible element of the device and a port-ion of the tauting means, being omitted. Figure 2 is a view in vertical sectional elevation of the complete device with certain of the parts shown in elevation, the section being` taken at a line corresponding with the line 2-2 on Fig. 1 and viewed in the direction vof the arrows, this view showing a pipe clamped in place in the device; and Figure 3. an end view of the device, the device being viewed from the left-hand side of Fig. 2.

The preferred illustrated embodiment of my invention comprises a base 4 at which the device is adapted to be secured to a support, as for example to the top of a table,

as by bolts 5 passing through openings 6 in the base 4. rlhe base 4 is shown as formed integrally with upwardly extending parallel, spaced apart, plate portions 7 integral with they bottom plate portion 8 of the base 4 and connected together by an angular web 9 rising from the plate portion 8 with its portion 10 extending generally parallel with the plate portion 8 and presenting a slot 11 in its outer end. The

" plate portion 8 in alignment with the space between the plate portions 7 is slotted, as represented at 12, with a web portion 13 connecting together the ends of the plate portions 7.

The outer faces of the plate portions 7 are recessed, as represented at 7a, to receive jaw members 14 secured thereto as by the bolts l5 and presenting toothed seating surfaces 14a at w ich the article, as for example Serial No. 97,628.

the pipe shown at 16, to be clamped in the vise, bears.

Located in the space between the plate portions 7 and directly below the web portion 13, is a rock lever 17 pivotally supported at oney end, as represented at 18, to the plate portions 7 and provided at its free end with a head'19, the under surface of which, and represented at 20, is semi-cylindrical.

rlhe device also comprises a flexible element 21, shown as a chain, for clamping the article, as for example the pipe 16, firmly against the bearing surfaces 14a, one end of this chain being adapted to be introduced into the recess 11 to interlock at one of the cross pins 22 of the chain, with the arms 23 of the web portion 10 located at opposite sides of the recess 1l. rlhe other end of the chain which passes over the object 16 as shown in Fig. 2, extends beneath, and in engagement with the head 19 and connects at its extremity with the lever 17 between the head 19 and the pivot 18, as by means of the pivot pin 24.

It will be understood from the foregoing that by arranging the parts Aas described, pressure exerted downwardly against the lever 17 preferably at its head portion 19, which operates to swing this lever in counterclockwise direction in Fig. 2 operates to pull downwardly on the free end of the chain and thereby tightly, grip the object 16 against the bearing surfaces 14a and by reason of the leverage action thereby afforded against the free end of the chain, a relatively slight amount only of su'h pressure is required to exert a powerful clamping action against the object 16, it being noted that wear on the chain at the portion thereof engaged by the head 19 is practically negligible because of the absence of friction between these parts. Any suitable means for actuating the lever 17 may be provided, those shown comprising an actuating threaded rod 25 which has screw threaded engagement with an opening 26 in the web 13. the outer end of this rod being equipped with a handle for operating it, shown preferably as a forked member 27 pivotally supported at. inwardly extending projections 28 on the arms 29 thereof, in diametrically opposed openings 30 in the outer head portion 31 of the rod, this construction permitting the handle 27 While l have illustrated and described al particular construction embodying my invention. I do not Wish to be understood as intending to limit it `thereto as the same may be variouslyA modified and altered Without 'departing from the spirit of my invent-ion.

`What I claiin as nev, and desire to se'- cure by Letters Patent is:

' AIl. A -vise comprising a base having a seat- 'ing .surface Vfor the article to be clamped,
